Optic14n

Canonicalises URLs.

Installation

Add this line to your application's Gemfile:

gem 'optic14n'

And then execute:

$ bundle

Or install it yourself as:

$ gem install optic14n

Usage

Parse a BLURI like this:

  bluri = BLURI('http://somewhere.com/?a=1&b=2&c=3')

Canonicalize it according to the Previously-Established Rules thusly:

  bluri.canonicalize!

You can also do site-specific stuff if you know some of the querystring will be valuable

  bluri.canonicalize!(allow_query: :all)
  bluri.canonicalize!(allow_query: [:a, :c])
  # or
  bluri.canonicalize!(allow_query: ['a', 'c'])

The previously-established rules

This is a gem for canonicalising HTTP URIs such that we can boil our input set of URIs down to something that is much smaller than it would otherwise be. We do this aggressively by:

  • lowercasing URIs
  • removing query strings (unless told otherwise)
  • removing fragments
  • escaping and unescaping various characters and escape sequences according to RFC3986
